Short description:

This book will provide a fascinating read for anyone interested in number theory, infinity, math art, and/or generative art, and could be used a valuable supplement to any course on these topics. Along the way the author will demonstrate how infinity can be made to create beautiful ?art?, guided by the development of underlying mathematics.

Long description:

This is a book about infinity ? specifically the infinity of numbers, and how one kind of infinity is greater than all the rest. Along the way the author will demonstrate how infinity can be made to create beautiful ?art?, and how this process can help us to understand the fundamental nature of numbers. This book will provide a fascinating read for anyone interested in number theory, infinity, math art, and/or generative art, and could be used a valuable supplement to any course on these topics.


Features



  • Beautiful examples of generative art.

  • Accessible to anyone with a reasonable high school level of mathematics.

  • Full of challenges and puzzles to engage readers.
